7 Claims.

This invention appertains to buildings, and more particularly to window constructions, ostensibly of the sliding sash type.

One of the primary objects of my invention is 5 to provide novel means for mounting the sashes in the window frame, whereby the lower sash can be readily tilted and locked in an adjusted position relative to the sliding upper sash to bring about the thorough and efiicient ventilation of a room. Another salient object of my invention is the provision of means whereby both the upper and lower sashes are freely removable from the window frame, so that the opposite faces of the panes of the sash can be quickly and conveniently cleaned without danger to the operator.

Another important object of my invention is the provision of means whereby the lower sash can be held in a reversed position in the window frame, so that this sash can be held rigid, if so desired, during the washing of the outer face of the window pane.

A further object of my invention is the provision of novel sliding plates upon which the lower by the upper sash can be swung into a room or removed entirely from the frame, or reversed, when the upper sash is in its extreme lowered position.

A further important object of my invention is the provision of novel meansfor detachably holding the slide plates in their lowered position against accidental movement when the upper sash is swung into a room or removed from the slide plates.

,A further object of my invention is the provision of means for automatically releasing the slide plates when the upper sash is swung back to its vertical normal position, whereby the sash can be 40"freely slid to its raised closed position.

A further object of my invention is the provision of novel means for arranging the sashes relative to themselves and to the frame, whereby an air-tight and weatherproof window will be had.

A further object of my invention is the provision of novel means for holding the sashes in their various positions so that the sashes cannot be manipulated by persons standing on the outside of the room.

A still further object of my invention is to provide a window construction of the above character which will be of an especially simple and durable construction, and which can be incorporated in a new or old building at an economical price.

With these and other objects in view, the incorners of the upper sash rest, with means wherevention consists in the novel construction, arrangement, and formation of parts, as will be hereinafter more specifically described, claimed, and illustrated in the accompanying drawings, in whichdrawings:

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter F generally indicates a window frame in which is mounted an upper sash l and a lower sash II.

In general, the window frame F and the sashes Ill and II are of ordinary construction, and thus the window frame F includes the side stiles I2, the lintel l3, and the sill, l4. Each of the sashes include the usual side, top, and bottom rails, which are constructed to receive and hold the window panes.

The inner faces of the stiles l2 of the window frame F can be provided with a filler or guide strip I and a blind stop or strip IS. The filler or guide strip l5 extends from the extreme top of the window frame to the sill. This top sash is of a less width than the bottom sash, as can be seen by referring to Figure 1 of the drawings, and passes freely between the filler or guide strips 15.

Any preferred means can be provided for normally holding the top sash in its raised elevated In the present instance, I have illustrated the use of thin metallic bands H, which are adapted to be wound off and on spring drums carried by the window casing. The lower ends of these metallic bands I! carry the slides l8 upon which the top sash Ill rests, as will now be set forth.

In lieu of connecting the spring bands H or the sash cords directly with the top sash, I utilize the novel slides or plates 18 on each side of the window. These slide plates are of substantially the same length as the top sash, and r the same can each be formed from a single piece of sheet metal folded into the desired form.

Each slide plate l8 includes inner and outer walls I9 and 20 connected by a rear wall 2|. The outer wall 20 is folded at right angles, and is then bent back in parallel relation to the inner and outer walls, as at 22. This forms a reenforcement and a guide, as will be later set forth. The inner side wall I9 is provided with an inturned flange 23, which is arranged in spaced relation to the bent back portion 22, defining in connection therewith a guide slot 24. The wall IQ of each slide plate is cut away at the top for the reception of the sash cord or metallic strip I1, and this cutaway portion allows the free sliding of the slide plates past the cord pulleys when such is utilized. Suitable means such as a screw or pin 25 is provided for anchoring the lower ends of the sash cords or strips I! with the slide plates. When the slide plates are in their raised position, the same are confined against lateral shifting movement by the stop strip l6 and the filler strip IS. The lower ends of the outer walls 20 of the slide plates have formed thereon inwardly extending supporting feet 26, on which the lower corners of the upper sash l0 normally rest.

When the upper sash is lowered and moved past the lower ends of the weather strips 2'? carried by the filler strips l5, the sash can be swung into the room, or can be quickly lifted off of the feet 26 so that the opposite faces of the window pane can be conveniently and expeditiously cleaned. This also facilitates the assembling of a window.

When the top sash is in its swung open position, or is removed from the frame, means is provided for automatically holding the slide plates in their lowered position. This means includes rocking latches 28 located within and carried by the slide plates. The lower outer corners of the latches 28 are provided with noses 29, which are loosely mounted within openings 30 formed in the rear wall 2| of the slide plates l8, so that the said latches can swing back and forth in the slide plates.

In view of the fact that the upper ends of the latches are at one side of the noses 29, the latches normally tend to swing down and out of the slide plates, and under the lower ends of the weather strips 21 for engagement therewith. When the latches swing under the weather strips, upward movement of the slide plates will be prevented, as the latches engaging the weather strips resist said upward movement.

The swinging movement of the latches 2B is limited by outwardly extending pins 3| carried by the upper ends of the latches. These pins work back and forth in slots 32 formed in the slide plates and protruding a considerable distance beyond the inner faces of the slide plates.

The outer ends of the pins 3| are arranged in the path of the upper sash, and consequently when the upper sash is swung into a vertical position, the sash will engage the pins and move the latches 28 away from underneath the weather strips 21, thus permitting the free sliding movement of the slide plates and the top sash.

The weather strips 21 are formed from sheet metal and are folded back upon themselves to define an outwardly extending rib, and the edges of the rib are adapted to be inserted within suitable slots within the window frame.

Novel means is provided for holding the upper sash in any adjusted open position, and in its closed position. This means includes a springpressed latch bolt 33 carried by one side of the window frame. The latch bolt 33 is normally urged out of the frame toward one edge of the top sash, and this edge is provided with a rack bar, or a series of openings 34 for receiving the bolt. The rear end of the bolt has formed thereon an eye 35 through which extends one end of a bell crank shaped lever 36. This lever, at its angle, bears against the window frame and rocks thereon, and the lower end of the lever is connected to a slide block 31 carried by the front of the window frame. This slide block is provided with a finger-piece 38. Obviously by manipulating the slide block the latch bolt can be moved out against the tension of its spring.

Particular attention is now directed to the lower sash II, and while this sash-can be made to slide up and down, I prefer to have the same simply set into the frame for swinging movement. Hence, no stop strip is provided for the lower sash. The inner faces of the stiles of the window frame can carry, however, weather strips 39, the ends of which are also preferably set into slots in the window frames. The'weather strips 39 are folded to provide front ribs 40, which extend out parallel to' the inner faces of the stiles for fitting in grooves 4| in the lower sash. These strips 39 are further folded to form, rearwardly extending ribs 42 (see Figure 7), to fit in the guide slots 24 of the slide plates 18, when the same are in their lowered position.

The window sill can carry a resilient piece of weather stripping 43 against which the lower rail of the bottom sash can rest.

To permit of the holding on the lower sash in an adjusted swung open position, the sides of the stile carry keeper plates 44. The keeper plates have a row of keeper openings 45 therein. The openings 45 are formed relatively deep, and

the keeper plates immediately above the row of deep keeper openings are provided with a single shallow keeper opening 46. The side rails of the lower sash l I each carry outwardly spring-pressed latch bolts 41. When the sash is in its closed position, the bolts are adapted to engage the innermost of the keeper openings 45, and when the sash is swung open the latch bolts 41 can engage in either one of the other openings 45.

A single means is provided for operating the a latch bolts 41, and the same may consist of an angle-shaped operating lever 48, pivoted at one end on a pin 49 carried by. the sash. The outer end of the lever extends beyond the upper face of the top rail of the sash, and has formed thereon a finger-piece 50. Rockably connected to the lever, at its angle, are oppositely extending bell crank shaped levers 5|. These levers 5| are received in slots on the window sash, and are pivoted at their angles on pins 52 carried by the sash. The lower ends of thelevers 5| are operatively connected to the latch bolts41. Consequently, upon upward swinging movement of the operating lever 48, the latch bolts can be moved inwardly against the tension of their springs, and

away from the keeper plates 44.

In order to prevent the unauthorized operation of the latch bolts 41, by persons on the outside of the window, when the windowis in a partially open position, I provide a spring-pressed push rod 53. This push rod 53 is carried by one side rail of the lower sash, and is disposed at right angles to the adjacent latch bolt 41. A transverse slot 54is formed in the push rod, and normally this slot is out of alinement with the adjacent lever 51. When it is desired to manipulate the latch bolts.41, the operator presses inwardly upon the push rod 53 until the groove 54 alines with the lever 5!, and when this takes place the lever can move into its fullest extent, allowing proper manipulation of the latch bolts.

In some instances, it may be desirable to re move the lower sash and reverse the position thereof, so that the sash can be held rigid during the washing of its normally outside face. This can be easily accomplished by simply lifting the sash from the window frame and reversing the position thereof. When the position of the lower sash is reversed, the latch bolts 41 are disposed in the path of the keeper socket or opening 45, and consequently the latch bolts 41 will ride therein and hold the lower sash solid. As this opening 45 is of a shallow depth, the bolts will not move outwardly for a very great distance, and consequently a lever 51 will still be in the slot 54 of the push rod 53. This will permit manipulation of the latch bolts without further operation of the push rod.

In Figures 10 and 11 I have illustrated a slightly with upstanding arms 69 and10.

modified form of latch for holding the lower sash in its completely closed position or in its partially swung open position. ,In these figures the lower sash is generally indicated by the reference character 60, and, as shown, the same includes the 5 side rails 6| and the top rail 62. The outer edges of the side rails 6| are slotted, as at 63, to receive the operating levers 64, which are rockably mounted intermediate their ends on pivot pins 65 car-,, ried by the sash rails.

The lower ends of the levers 64 have formed thereon or secured thereto outwardly extending latch noses 66, which are adapted to engage keeper plates on the sides of the window frame.

These plates can be the same as the plates 44" shown in Figures 2, 3, and 5.

The upper ends of the levers 64 are hooked through openings formed in the outer ends of actuating slide plates 61. The inner ends of. these plates are arranged in over-lapping relation and are received within a metal guide 68 secured to the top or midrail 62 of the lower sash. These slide plates 61 are provided respectively The arms can be provided with removable finger-pieces H.

As illustrated, the arm 53 extends through a slot 12 formed in the top slide plate 51. Leaf springs 13areemployed for engaging the lower ends of the levers 64 so as to normally urge the latch noses 66 into engagement with the keeper" plates. Obviously, by moving the finger-pieces 1| toward one another, the levers 64 can be rocked so as to bring the noses out of engagement with the keeper plates. A finishing strip 14 is utilized for the top: sash rail 62, so as to hide the a a modified form of means for holding the slides and, consequently, the upper sash in a locked adjusted position. This means can be utilized in lieu of the upper sash holding means illustrated in Figures 1 and 4.

As in the previous form, the slides for the upper sash are mounted between a parting strip 15 and an outer or blind stop 16. In Figures 13, 14, 15, and 16, the slides for the upper sash are generally indicated by the reference character 11, and the inner edge of one slide is provided with a series of spaced openings 18, the purpose of which will be later set forth.

The parting strip or stop 15 has rockably mounted on its inner face by means of a pivot pin 19, a latch lever 80, and the upper end of this lever is offset, as at 8!, to extend into a cavity 82 formed in the inner face of said parting strip 15. The upper end of the lever has formed thereon a latch nose 83, which is adapted to extend through an opening 84 in the parting strip, whereby the nose can engage any one of the openings 18 in the sash slide 11. A leaf spring 85 is utilized for normally urging the nose 33 through the opening 84 toward the sash slide 11. The spring 85 has one end anchored to the window frame, and its other end bears against and is secured to the lever 80 above the pivot point of said lever. The extreme lower end of the lever 80 has formed thereon a laterally extending arm 86, the inner end of which is provided with an eye 81. A push rod 88 is provided for engaging the eye, and this rod is mounted within a suitable casing 85 carried by the window frame. The outer end of the rod extends beyond the front face of the window frame and is provided with a manipulating finger-piece 90.

By pushing upon the finger-piece 90, the push rod will be operated for rocking the lever 80 on its pivot 19, and thereby swing the nose 83 away from its slide plate Tl against the tension of the spring 85, whereby the slide plates can be released to permit adjustment of the upper sash.

If preferred, the lower ends of each slide plate 11 below the supporting feet 9| for the upper sash can be provided with a depending lug 92, which is adapted to fit in rear of a stop piece 93 on the sill, when the upper sash and the slides are in their extreme lowered position. This prevents accidental outward swinging movement of the lower ends of the slides.

Referring back to Figure 10, in lieu of providing the latch noses 66, I can connect the lower ends of the levers 64 to latch bolts similar to the construction shown in Figure 3 of the drawings.

In Figures 13, 14, and 15, the weather strips have been eliminated for the sake of clearness.
